Blockchain

Image
  A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. The decentralised database managed by multiple participants is known as Distributed Ledger Technology (DLT). Bitcoin was designed to solve this problem by using a specific type of database called a blockchain. Most normal databases, such as an SQL database, have someone in charge who can change the entries. Blockchain is different because nobody is in charge; it’s run by the people who use it. What’s more, bitcoins can’t be faked, hacked or double spent so people that own this money can trust that it has some value. Every transaction in this ledger is authorized by the digital signature of the owner, which authenticates the transaction and sa

Big Data Analytics

  Big data analytics examines large amounts of data to uncover hidden patterns, correlations and other insights. With today’s technology, it’s possible to analyze your data and get answers from it almost immediately an effort that’s slower and less efficient with more traditional business intelligence solutions.The new benefits that big data analytics brings to the table, however, are speed and efficiency. Whereas a few years ago a business would have gathered information, run analytics and unearthed information that could be used for future decisions, today that business can identify insights for immediate decisions. The ability to work faster  and stay agile gives organizations a competitive edge they didn’t have before. Most organizations have big data. And many understand the need to harness that data and extract value from it. Today, there are millions of data sources that generate data at a very rapid rate. These data sources are present across the world. Some of the largest sour

LoRa Technology

LoRa (s is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. LoRaWAN is a protocol specification built on top of the LoRa technology developed by the LoRa Alliance. It uses unlicensed radio spectrum in the Industrial, Scientific and Medical (ISM) bands to enable low power, wide area communication between remote sensors and gateways connected to the network. This standards-based approach to building a LPWAN allows for quick set up of public or private IoT networks anywhere using hardware and software that is bi-directionally secure, interoperable and mobile, provides accurate localization, and works the way you expect. LoRa network is consist of gateways, network servers and End devices. The network topology  used is star of stars. End devices are also known as motes and gateways are known as base stations or concentrators in LoRa network system. End devices and Gateways are connected wirelessly using ISM bands specified with single hop.Gateways

Data Science

  Next up in the list of latest technology concepts is not surprisingly Data Science. Data Science is the technology that helps to make sense of complicated data. You know that data is produced in a humungous amount every day by companies. This includes business data, sales data, customer profile information, server data, and financial figures. Most of this data is in the form of huge data sets that are unstructured. The role of data scientists is to convert these unstructured data sets into structured datasets. Then, these data sets can be analyzed to identify patterns and trends. These patterns are useful for understanding the company’s business performance, customer retention, and how these areas can be improved. Data science is an interdisciplinary field focused on extracting knowledge from data sets, which are typically large and applying the knowledge and actionable insights from data to solve problems in a wide range of application domains. The field encompasses preparing data f

Cyber Security

Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes. Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.  Cyber security is important because government, military, corporate, financial, and medical organizations collect, process, and store unprecedented amounts of data on computers and other devices. A significant portion of that data can be sensitive information, whether that be intellectual property, financial data, personal information, or other types of data for which unauthorized access or exposure could have negative consequences. Organizations transmit sensitive data across networks and to other devices in the course of doing businesses, and cyber securit
